11. Install & Configure Symfony
Composer

12. Run Symfony Creating vhost

13. Composer Introduction
Composer is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.
To install Composer go to and follow instructions.

14. Composer Install Symfony with Composer:
php composer.phar create-project symfony/framework-standard-edition my_project_name
php composer.phar create-project symfony/framework-standard-edition my_project_name “3.2.*"
composer create-project symfony/framework-standard-edition symfony-project "3.2.*"
Installing symfony/framework-standard-edition (v3.2.8)
- Installing symfony/framework-standard-edition (v3.2.8)
Downloading: 100%
Created project in symfony-project
Loading composer repositories with package information

15. Run Symfony
To check configuration
symfony.localhost/config.php

16. Run Symfony Setting up permissions
Linux
HTTPDUSER=`ps axo user,comm | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\ -f1`
sudo setfacl -R -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX var
sudo setfacl -dR -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX var
macOS
rm -rf var/cache/*
rm -rf var/logs/*
HTTPDUSER=`ps axo user,comm | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\ -f1`
sudo chmod -R +a "$HTTPDUSER allow delete,write,append,file_inherit,directory_inherit" var
sudo chmod -R +a "`whoami` allow delete,write,append,file_inherit,directory_inherit" var
Windows
umask(0002); // This will let the permissions be 0775
// or
umask(0000); // This will let the permissions be 0777

19. First Steps With The Framework
Symfony Overview
First Steps With The Framework

20. The Bundle System What is a Bundle?
set of files within a directory designed to imlpement a
single feature
each bundle has its own namespace
\<Vendor Name>\(<Namespace>\)*<Class Name>

21. The Bundle System The bundle class name must follow five simple rules:
Use only alphanumeric characters and underscores;
Use a CamelCase name;
Use a descriptive and short name (no more than two words);
Prefix the name with the concatenation of the vendor (and optionally the category namespaces);
Suffix the name with Bundle.

22. The Bundle System Example of valid bundle names: Namespace
Bundle Class Name
Stenik\BlogBundle\StenikBlogBundle
StenikBlogBundle
Stenik\ServicesBundle\StenikServicesBundle
StenikServicesBundle

23. Directory Structure Directory Description var/ logs and cache files
vendor/
dependecies (bundles)
src/
the project’s code (own bundles)
Web/
Web root directory, application index
app/
Application Kernel and configuration files
bin/
Symfony console
tests/
Automatic tests

24. Symfony Project Overview
app/AppKernel.php
Is the most important file of our project
All bundles are registered/activated in AppKernel
class AppKernel extends Kernel {
public function registerBundles() {
$bundles = [
new Symfony\Bundle\FrameworkBundle\FrameworkBundle(), ];
//TO DO }

25. Symfony Project Overview
app/AppKernel.php
AppKernel also provides configuration for different environments
class AppKernel extends Kernel {
public function registerBundles() {
//TO DO
if (in_array($this->getEnvironment(), ['dev', 'test'])) {
$bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle(); }
Each environment should have its own config file suffixed with the name of the provided environment, e.g.: config_dev.yml
Each environment creates its own cache and log files in var/cache and var/log

26. YAML
YAML is:
human-readable data serialization language like json and xml, but easier to read
based on key: value
used for Symfony configuration

27. Symfony Project Overview
app/config/config.yml
Application main config file for application settings
framework:
templating:
engines: [‘twig’]
imports:
- { resource: parameters.yml }
- { resource: security.yml }
- { resource: services.yml }
- { resource: }

28. Symfony Project Overview
app/config/parameters.yml
Infrastructure-related configuration like database settings and mail service
parameters:
database_host: localhost
database_name: symfony
dabatase_user: root
database_pass:
custom_param: param_value

29. Symfony Routing app/config/routing.yml
Contains mapping between controllers and routes
user_profile:
path: /user/profile
defaults: { _controller: AppBundle:User:profile }
services_bundle:
resource:
type: annotation
prefix: /{_locale}
requirements:
_locale: "[a-z]{2}"

30. Symfony Routing Parameters
app/config/routing.yml
_controller
This parameter is used to determine which controller is executed when the route is matched.
_format
Used to set the request format (read more).
_locale
Used to set the locale on the request (read more).

31. Trying some code
git clone

32. Summary
Symfony is leading PHP framework to create websites and web applications. Built on top of the Symfony Components
A bundle is similar to a plugin in other software, but even better. The key difference is that everything is a bundle in Symfony, including both the core framework functionality and the code written for your application. Bundles are first-class citizens in Symfony
